About this Duplicate Word Remover
The Duplicate Word Remover creates a de-duplicated word sequence by keeping the first occurrence of each word and removing later repeats. It can help clean keyword lists and short word collections where uniqueness matters more than sentence grammar.

How the calculation works
Words are compared case-insensitively after surrounding punctuation is ignored for the duplicate key. The first written form is preserved in the output. This can change normal prose, so it is best for lists and keyword-style text.
How to use it
- Paste a word list or text.
- Choose Remove duplicate words.
- Review the unique sequence and duplicate count.
Practical example
“red blue red green blue” becomes “red blue green”.
